Science: Separating Materials

This term we have been investigating how to separate materials.  We have used a range of equipment, experimented and tested out our ideas.  We are working hard on explaining our thinking and results.
 

We went on to look at several different separation methods:
Filtering
Sieving
Evaporating

The children even made their own filters!

Some of the water did look cleaner after being through the filter but the children still weren't keen to drink it- I don't blame them!  Very sensible children! 

Separating solid materials


 

We learnt to: 
-compare and group materials based on their properties (e.g. hardness, solubility, transparency, conductivity, [electrical & thermal], and response to magnets).

-describe how a material dissolves to form a solution; explaining the process of dissolving.

-describe and show how to recover a substance from a solution.

-describe how some materials can be separated.

-demonstrate how materials can be separated (e.g. through filtering, sieving and evaporating).

-demonstrate that some changes are reversible and some are not.

-explain how some changes result in the formation of a new material and that this is usually irreversible.

-discuss reversible and irreversible changes.

-give evidenced reasons why materials should be used for specific purposes.
